Apple has yet to explain why various paid apps are being given away for free, nor is it clear how many days the “free download” period will last. CNET, along with various others news sites, has reached out to the Cupertino company for comment, and is currently still waiting for an official response.

Many believe the special promotion to have something to do with the app store’s fifth year anniversary. It is speculated that more free games and apps will begin popping up this week.
